SQUARE AND BEVEL STRUCTURE.

Speccaton of Letters Patent.

Patented Aug. 1o, A1920.

Application filed .Tune 4, 1919. Serial No. 301,684.

To all whom t may concern Be it known that I, FREDERICK CONRAD NIEBLTNG, a citizen of the United States, residing at Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Square and Bevel Structures, of which the following is a speciiication.

` My invention relates to improvements in square and bevel structures for carpenters use, and the object ofmy improvement is to produce a square and bevel ystructure in which the handle or body part and the blade part are relatively one to the other so as to serve either as a square or a bevel and when in position for use as a bevel can be set for f 't 'l f ld ll rhiferent angles, the parts being o aae when not in use to a closed position so as to be relatively compact, and furthermore, having means for positively preventing a complete separation or disconnection of the parts.

In the accompanying drawing Figure 1 is a side elevation of my improved square and bevel structure showing the parts adjusted for use as a square.

VFig. 2 is an end elevation of the same.

Fig. 3 is a side elevation showing the parts adjusted for use as a bevel.

Fig. l is a sectional view on the line 4 4 of Fig. 2.

Fig. 5 i sectional view on the line 5 5 or" Fig. 1, beinO' on an enlarged scale.

Fig. G is a sectional view on the same scale as Fig. A1 that differs from the said ,Figa 4- in having the parts adjusted or folded to the closed or compact position, being` inv convenient position for stowing away, as in a tool chest.

My improved square and bevel structure comprises a handle or body part 10 that serves as the Xed member and a member that is movable relatively to the said fixed member or part 10 in the form oi a blade part 11, which parts are interconnected in such a manner so as to be usablev either as a square, as shown in Fig. l or as a bevel, as shown in Fig. 3, and can be closed together, as shown in Fig. 6, into compact form, and the parts are provided with clamping means for retaining in either of the positions mentioned in the form of a clamping bolt 12 and a clamping nut 13, the latter being preferably some form of wing nut, as shown.

The handle part 10 is of rectangular form adjustable so that they can be sethandle part 10 of two mating parts, each of which comprises a metal body frame member 14 having a wooden handle scale 15, the two Jframe members 14 meeting along' the lower edge portions 1G and being held t0- gether by a plurality of rivets 17. Above the said lower edge portions 16 the opposed portions of the frame members lll are recessed or cut away so as to provide the slot 18 that is a tit for the blade part 11. Thus the handle part 10 is closed along the lower end by the meeting lower edge portions 16 and is open throughout the rest oi the struc ture to the extent of the opening provided by the slot 18.

The upper end portion of the handle part 10, remote from closed end 16, is provided with a stop pin 19 that extends across the slot 18 and the said slot 18 is also crossed by the clamping bolt 12.

As shown in Fig. 1, with the parts adjusted for use as a square, the blade part l1 extends outwardly toward the right oi2 the upper end portion of the handle part 10, In this position the clamping bolt 12 is located to the right or" the middle of the handle part 10, being on or adjacent the forty-five degree line extending downwardly and toward the left from the upper right hand corner 20. The location of the stop pin 19 is appreciably below the transverse line or plane that extends across the axis of the clamping bolt 12 as to elevation or position in the longitudinal direction of the handle part 10, and the location thereof transversely of the handle part 10 is relatively close to the left edge or end face 21.

The stop pin 19 serves as one positioning member for positioning the parts when adjusted for use as a square.

The clamping bolt 12 serves also as such a positioning member and likewise serves as a locking device in coperation with the clamping nut 13.

The blade part 11 is an elongated rectangular structure of sheet material that fits in the slot 18 and for coperation with the u closed position, as .shown in VFig.Y 6.

vvin parallelism handle part 10 is provided short openslot from the left end or edge 23 forv engaging with the stop pin 19, and is provided with a closed slot of peculiar form 'that serves as The said main part 2a servesv as the guide slot for the bolt 1 2 when the partsA are inv position lfor use as a bevel, Ias shown in Fig. 3, and also serves as the Yreceiving slot ior the said bolt 12 when theparts are in the When being brought to the yclosed position mentioned the outer, right hand end portion 26 of the bladerpart 11 is swung downwardly and inwardly relatively to the handle part 10, guided by the bolt 12 and main part 241701? the slot, until the parts are in parallelism and theouter lower corner 27 is received in the slot 18 and housed therein, the nut 13 being finally tightened to hold the parts. rlfhus when in the closed position the portion of the blade part 11 that is housed in the slot 18 is generally in the form of a rectangular zone that includes the lower outer corner 27 and extends in- Y wardly along the lower edge 25 from the said corner. The parts are constructed and-arranged so that in swinging the blade part 11 `relatively tothe handle part 10 the bolt 12 serves as a pivot and the pivotal member s. for coperating therewith is the outer end l part or wall portion 28 of the main part 24 of the closed slot.

rlhe closed slot mentioned 'comprises in addition to the main part 211 an auxiliary slot 29 that is positioned in the lett or inner end portion 30 ofthe blade part 11 that is relatively short, is directed in parallelism with the longitudinal axis ot the blade part 11, and, as shown, is actually positioned substantially along the said axis, and which, furthermore, like the main part 24, is a lit for the clamping bolt 12.

The closed slot Vmentioned 'is completed by means of a short interconnecting part 31 that connects the inner or leit ends of the main part 2li and the auxiliary part 29.

In shifting the parts from the position for use asa bevel to the position for use as a square the blade part 11 is moved toward the right relatively to thehandle part with Y the bolt 12 moving along the. main partA 24 of the slot until thelimit of such movement with a relatively 22 that extends inwardly `across one edge,

asians? is reached by the bolt abutting against the inner end wall 32 of the slot, when by a sidewise movement the blade part 11 is pushed inwardly along the handle slot 18, the bolt 12 traveling along the interconnecting part 31, until the bolt 12 is brought into registration with the inner or lett end of the auxiliary part 29. The parts are then brought to the iinal position by an inwardly directed longitudinal movement of the blade part11,the clamping bolt 12 traveling along the auxiliary part29 and the open recess 2 2 of the blade part 11 engaging with the stop p in 19, the nut 13 being tightened 'if desired to lock the parts in the adjusted position. Y

rlhe .upper edge portion 33 of the blade part 11 may be provided with scale marl*- ings, as shown, the said portion 33 being always exposed and available for use as a scale in all positions of the parts.

l claim as my invention 1. A square and bevel structure comprising a handle part of appreciable thickness and provided with a transversely directed slot and a blade part of sheet material fitting the said slot, a pair oit positioning pin devices crossing the said slot and positioned in spaced relation along a line directed diagonally of the handle part, and the said blace part being provided with a set of slots for engaging with the said positioning pin devices for positioning the parts for use for engaging with the other of thesaid devices.

, 2. A square and bevel structure comprising a blade part of sheet material and a handle part that is slotted for receiving the said blade part, a pair of positioning pins extending across the slot in the handle part, the blade part having a slot that opens inwardlyv from one end for separably engaging withone of the said pins and having in the body portion connected slots for the other of the said pins, comprising a main portion parallel with one edge, a second portion to one side of the said main portion, and a connecting portion interconnecting the said main portion and second portion.

3. ln a square and bevel structure as described in claim 2, and the slot in the handle part being extended longitudinally and suitably to receive the major portion oi the blade part in one position of the parts.
